This USB gadget is known as the SentrySafe USB Safe.
Having a home safe can be a nice way to protect personal valuables such as paper documents and really expensive jewelry but the SentrySafe goes a step further by including a USB port.
This is so that you can lock electronic data (eg hard drives) within the safe and you can access the contents of the data without ever having to open the safe door. The SentrySafe is both a waterproof and fireproof safe and will thus protect your information from these two types of disasters.
Of course, the safe won’t do anything to protect the data on the hard drive from a home burglar, so if you’re really concerned data security, you may want to also invest in encryption software if you haven’t done so already.
